MOSAIC'COVERING FOR WALLS, COLUMNS, AND THE LIKE.-

Application filed May 14, 1910. Serial No. 561,407.

- formed from reinforced concrete, which invention consists of a plate having openings andforrning a frame or foundation, on which the mosaic stones are fastened by means ofprojecting pieces of button shape 1. provided on the back of the mosaic stones and which engage or lock in the openings in the plate.

In the drawings. several applications of the invention are shown.

Figure 1 is a view of a mosaic wall constructed according to the present invention. Figf2 a section on the line Ali of Fig.

- 1. Fig. 3 represents a single stone showing the structuralparts. Fig. 4 shows a column in cross section. Fig. 5 shows a reinforced concrete wall in section with the plate on Fig. 6 is a similarview showing thefplate embedded in the wall, and Fig. 7 represents a square column in perspective. p

The mosaic construction consists preferably of a sheet metal plate a which contains theopenings b apportioned over the plate in accordance with the desired arrangement of the stones of the mosaic.

Each stone 0 is provided on its back with a button shaped pieced which serves a'for securing the stone to the plate. The openings I) extend downward in the form of slots f in which the button-pieces of the stones 0 are inserted, which hold the stones firmly against the plate. The openings 6 of the plate a can ofcourse have many differenti Specification of Iietters Patent.

button shaped pieces of thestones by means of suitable ornamentation may themselves "form mosaic stones, so that the back also of such a mosaic Wall can be very tastefully worked up and so not only can a varied orriamentation of the front side be attained but also of the back of the wall.

By the use of half stones 9 (Fig. 1) and quarter stones h and in addition half stones 2' and quarter stones formed by dividing the whole stone s along a diagonal, the variety of the patterns to lee-made is increased to a great extent.

y securing the stones to the plate'by means of a button shaped piece on the back of the stones, each stone is automatically centered and firmly attached so that even when the mosaic wall is placed horizontally or inclined the button shaped pieces will not be easily damaged or broken oif.

The use of a metal plate as a foundation for the stones is especially advantageous, in reinforced concrete construction because the metal )late embedded in the mass of concrete orms itself a supporting element of the concreteconstruction.

By placing two mosaic walls opposite each other (Fig. 5) which are connected together by means of iron rods-7c a hollow form is constructed which can. be filled with concrete in order to obtain a concrete wall. It is therefore not necessary to provide special sides for the hollow form as the sides are provided by the metalplates of the mosaic construction. In a like manner is it possible to construct, polygonal .or round columns (Figs. 4 and 7) in which cases the plates are supportedby embedding iron rods 1 or the like in the mass of concrete.

The mosaic construction according to the present invention can however easily be connectedto a concrete wall (Fig. 6) by arranging the plate with the stones before introducin the mass of concrete ,in a suitable manner into the hollow'form;

The. above described formof the mosaic stones makes the construction-possible for all adaptable materials, such as colored clay, glass or the like, and allows of an expedis. tious arranging of the stones:

It is to be understood that slight changes in the form, proportion and 'minor details of construction may be resorted to without sacrificing any of the advantages or departing from the spirit of the invention.

I dercut extensions, substantially as described Having fully described my invention, what I claim is 1. In a concrete construction having a mosaic surface, the combination of a frame provided with a plurality of apertures; a plurality of blocks having undercut extensions passlng throu h said apertures and projecting beyond sa1d frame; and a filling of plastic material contacting with said frame and surrounding the projecting ends of said undercut extensions, substantially as described.

2. In a concrete construction having a inosaic surface, the combination of a frame provided with a plurality of apertures ha ing lockin extensions; a plurality of blocks having un ercut extensions passing through said apertures interlocking with the extensions of said apertures and projectin beyond said frame; and a filling of plastic material contacting I with said frame and surrounding the projecting ends of said un- 3. In ,a concrete construction having a mosaic surface,'the'combination of a frame provided with a plurality of T-shaped apertures a plurality of blocks having undercut T-shaped extensions passing through said apertures interlocking with the same and projecting beyond said frame; and a filling of plastic material contacting with said frame and surrounding the T-shaped projecting ends of said undercut extensions, substantially as described.

4. The method of producing a concrete construction having a mosaic surface, whichconsists in providing a frame with a plurality of apertures; passing the undercut extensions of a plurality of closely fitting blocks through said apertures and beyond said frame; and placing a plastic material in contact with said plate and around said undercut projecting extensions to hold said blocks in place, substantially as described.

In testimony whereof. I have aflixed my signature in presence of two witnesses.
